EMBOSSING AND VENDING APPARATUS Filed Sept 25. 1950 Patented Jan. 17, 1933 "GEORGE w. HEENE, or cLEveLAND, orno ruvnsossiNe AND VENDING APPARATUS Application filed September 25, 1930. Serial No. 484,274.

My invention is an improvement inembossing and vending apparatus and relates more particularly to a die hammer and actuating mechanism'therefor. i

The present invention is particularly adapted for use with an apparatus'such as is shownin my Patent No. 1,494,839, patented .May 20, 1924 in which any one of a'number of dies may be selectedby the operator and brought intoproper position between ablank and the die hammer and in which suitable mechanism is provided for advancing the blank for the next impression and for simultaneously lifting the hammer to a point where it may be dropped upon the selected die whereby the nextimpression may be nadeon the advanced blank. v j

It is an object of my invention tolift the hammer to a position where it maybe ,dropped upon a selected die for making an impression on a blank in such a manner that the downard movement of the hammer will not be .interfered with even though the lifting means has not been returned to its normal position fora subsequent lifting operation.

Another object of my invention is to predetermine the depth of an impression in the blank madeby a selected die. i

A further object of my invention is to eliminate a point'of dead center between an extension of the hammer and the hammer lifting mechanism during the movement of the latter in either of its directions. I

A still further objectof my invention is to enable an operator of this apparatus to lift the hammer for a number of successive impressions without necessitating the return of the hammer liftingmechanism to one of its extreme positions. I

Further objects andadvantages of my in vention will become'more' apparent as the following description of an embodiment progresses, reference being-made to the accom-r panying drawing in which like reference characters are employed to designate like parts throughout the same. I

In the drawing: Figure 1 is a side elevation of an embodiment of my invention showing parts of the associated apparatus, and also showing the hammer and operating means in raised position in broken lines.

Figure 2 is a front elevation of the hammer showing the lifting means and other parts.

Figure 3 is a slightly enlarged front elevation of the hammer head.

Figure 4 is a detailed top elevation of an adjustable extension or finger carried by the hammer head. i

Figure 5 is aside elevation of the extension shown assembled in the hammer head, the latter being shown in cross-section.

Fi -ure 6 is a front elevation of a portion of the hammer head showing the extension in an adjusted position and illustrating the hammer in such position that it is about to be released by the lifting mechanism.

Figure 7 is a view similar to that of Figure.

6, except that the hammer is shown in the low- F 'ered position while the lifting means, in solid lines, is being returned to normal position.

.In broken lines I have indicated the position I of the lifting nose after it has passed out of engagement with the hammer extension.

In the drawing 1 have illustrated the preferred embodiment of my invention as applied to an apparatus disclosed in my Patent No. 1,494,839 patented May 20, 1924. In Figures 1 and 2 I have illustrated parts of the embossing and vending apparatus with which the present invention is associated. A blank 1 is "seated in a rotatable chuck 2 carried in the base 3. A series of radial normally lifted dies 4 are carried on a selector shaft 5, there-being suitable mechanism (not shown) for rotating the shaft in order to bring a selected die to proper position over the blank carried by the chuck. A hammerG is pivotally mounted at 7 on a standard 8 and terminates in an arm 9 which engages a spring pressed plunger 10 carried in the casing 11.

The forward end of the hammer terminates in a head 12 on which is formed a die engaging face 13. Extending upwardly from the head is an enlarged portion 14 on which may be secured one or more discs 15 of difierent thicknesses or weights, by means of a screw or bolt 16.. These discs are shown more clearly in Figure 3 and are removably attached of the lifting means when the hammer has to the enlarged portion14 of the head so that the user may select discs of a predetermined weight value in determining the force of the hammer impact and the depth of the impression of the die in the blank when the hammer is released from a predetermined raised position. 7 For instance, if a deep impression on the blank is desired all of the discs shown in Figure 3 may be secured to the head 14 to increase the weight of the hammer head On the other hand, if a lighter impression on the blank is desired one or more of these discs may be removed so that the hammer will drop with less force to make a lighter impression on the blank.

I have provided means carried by the ham mer head which may be adjusted axially and circumferentially, and which projects into the path of movement of the hammer lifting means. This usta-ble means is shown more particularly in Figures 3 to 7 inclusive and is shown in detail in Figures 4 and 5. This means includes a finger or extension 17 having a main body portion and an extension 18 which is preferably semi-circular in crosssection. The end face 19 of this extension is preferably inclined upwardly toward the hammer head as shown more particularly in Figure 5.

The extension 17 is adjustable axially and circumferentiallyin an opening 20 formed in the hammer head and may be secured in adjusted position in the opening by means of a set screw 21. The extension .18 carries markings 22 which may be in the form of shallow groovesor depressions formed in the material of the extension and spaced at predetermined intervals. Since the member 17 is movable axially in the opening of the head, the markings 22 may be made to register with the outer face of the head to indicate to the user a predetermined axial position of the member 17 into and out of the path of movement of the hammer lifting means.

The substantially diametrical face 24 of the extension 18 is indicated more clearly in Figures 3, 6 and 7, and since the member 17 is movable circumferentially in the head the upper edge of the face 24 may be brought into register with one or more of the markings 25 on the plate 26 secured to the head by means of the screw 27. In this way a predetermined angular position of the face 24 may be obtained so that the nose of the hammer lifting means engages only a limited portion of this face during the downward movement come to rest. This is illustrated more clearly in F 1gure 7. r

The hammer lifting means includes an operating lever 30, a shaft 31 and an arm 32.

33is provided with a stop 35 which overlies .6, there being no relative movement between the nose 33 and the arm 32 during this phase of the operation. As the arm 32 approaches the positionshown in Figures 5'and 6 the point'36 of the extension 18 formed by the converging walls 18 and 19, will: ride over the edge of the nose as shown in Figure 5. As this point clears the. nose, the hammer will drop freelyand exert an impact force on the die 4 positioned over the blank 1.. It will be noted that the nose 33 will not interfere with the downward movement of the hammer after it has once been released due to the in-- sion 18 for only a short distance in its 'downward movement since this wall is set at a.

slight inclination to a true vertical plane. In this manner the lifting means is ready to again lift the hammer for the next impact even though it has not been returned to its extreme limit of movement .in a downward 7 direction.

Various changes may be made in the details of construction and arrangement of parts Without departing from the spirit of the invention or the scope offthe appended claims.
